Rep. Marsha Blackburn said the Trump Justice Department is making the right move by suing California over the state's dangerous sanctuary policies.

The lawsuit -- which was announced by Attorney General Jeff Sessions Wednesday morning -- targets three recently-passed California state laws that allegedly interfere with federal immigration policies.

One of the laws limits state and local cooperation with Immigration and Customs Enforcement (ICE), while another prevents private companies from voluntarily cooperating with federal immigration enforcement officials.

"What they have done in California is basically say to citizens, 'We're going to take away your right to report people that you think are here illegally or people who are bad actors,'" Blackburn (R-Tenn.) argued on "America's Newsroom" Wednesday, calling these policies "astounding."

The Senate candidate suggested that many Democrats are more concerned about shielding illegal immigrants from deportation than they are about protecting American citizens.

Blackburn pointed to Oakland Mayor Libby Schaaf (D), who just made headlines by issuing a warning about impending ICE raids, allowing hundreds of criminal aliens to elude federal agents.

She said that move was "completely inappropriate," as it aids criminal illegal aliens and puts law enforcement at greater risk.

She added that House Republicans are ready to take action on immigration reform -- including sanctuary cities and the Deferred Action for Childhood Arrivals (DACA) program -- even if many Democrats are unwilling to come to the table.

"Secure the southern border, end chain migration, end the diversity lottery, get this wall built and make certain that our border agents and officers have everything they need," Blackburn said.

Former Acting ICE Director Thomas Homan said Tuesday on "The Ingraham Angle" that if Republicans and Democrats in Congress closed "loopholes" in the law that allow for "catch and release" and other perceptively problematic situations, the migrant caravans would cease to exist.
